Jizhong Energy - Phase II Xingdong Mine Integrated Communication Dispatch Project Successfully Delivered

Jizhong Energy Group Co., Ltd. (referred to as Jizhong Energy, stock code 000937) is a provincial state-owned sole proprietorship approved by the People's Government of Hebei Province. The company holds a listed company, Hebei Jinniu Chemical Co., Ltd., and owns 9 pairs of mines including Dongpang Mine, Xingtai Mine, Xingdong Mine, Gequan Mine, Zhangcun Mine, Xiandewang Mine, Shanxi Shouyang Duanwang Coal Chemical Company, Shanxi Shouyang Tiantai Coal Industry Company, and Zhangjiakou Guyuan Coal Mine, with a total approved production capacity of 11.71 million tons. Huabei Pharmaceutical, International Logistics, Hebei Logistics, Equipment Group, and Huabei Medical are five non coal subsidiaries, holding controlling stakes in two listed companies, "Jizhong Energy" and "Huabei Pharmaceutical". They also have a finance company, with industries distributed in 14 provinces and regions including Hebei, Shanxi, Shaanxi, Inner Mongolia, and Xinjiang, covering coal and new energy, pharmaceutical and health, chemical and new materials, modern services, and other fields. As of the end of 2022, the total assets are 240 billion yuan, with 100000 employees, and the headquarters is located in Xingtai City, Hebei Province.

Due to the fact that the Jizhong Energy Communication System has been in use for many years, the equipment is outdated and has a single function, and there is a serious situation of multiple systems running in parallel: the telephone system, monitoring system, broadcasting system, cluster intercom system, conference system, fire alarm system, etc. are all independent and do not have a unified management platform, resulting in current difficulties in operation and management. There is an urgent need for a new integrated communication system to replace the existing system, and requirements have been put forward such as integration of line and line, multi system integration and linkage, unified standards, flexible networking, higher system integration, easy expansion, provision of customized interfaces, and integration with many existing third-party platforms.

So Jizhong Energy conducted a public bidding for communication system renovation nationwide, with Xiaoben Technology and many domestic manufacturers competing on the same stage. With excellent integration of communication functions, integration and stability, they successfully became the equipment and service provider for Jizhong Energy's communication system renovation projects in multiple phases.

The Jizhong Energy Communication System Renovation Project - Dongpang Coal Mine Dispatch Project has been successfully delivered in December 2021. This is the Jizhong Energy Xingdong Mining Integrated Communication Dispatch Project, and Jizhong Energy has also put forward higher requirements:
